THE NATIONAL GEOGRAPHIC MAGAZINE © A. T. Schofield THROUGH A NARROW CLEFT THE NILE RUSHES TO MAKE THUNDERING MURCHISON FALLS Between Lake Victoria, its source, and these falls near Lake Albert, the infant river flows through such canyonlike walls, but below here it is a winding, lazy stream. The constant supply of water tapped from the great Lakes Victoria, Albert, and Edward forms a nucleus that keeps green the Nile's lower valley in the Sudan and Egypt. During the rainy season, mountain tributaries empty torrents into the Nile, spreading a rich coating of silt over farm lands. Vast new dams now impound much of this flood water and hoard it for irrigation.
